Latest progress in the study of nanoparticle-based delivery of the CRISPR/Cas9 system.

The CRISPR/Cas9 system has been harnessed to cleave a targeted DNA fragment via its Cas nuclease activity under the direction of guide RNA for rendering gene insertions, deletions, and point mutations in basic research and clinical applications. There are a number of vehicles, including lipofectamine, viruses, and nanoparticles, that can deliver the CRISPR/Cas9 system, but all these methods face numerous challenges during their application in life science contexts. Here, we focus on the delivery of CRISPR/Cas9 via nanoparticles because this method has shown great advantages in terms of safety, simplicity and flexibility.
